After I get Mechanical Level 4 is it safe to upgrade something else?
And if so what should I upgrade to level 2? Botanical or archeological? I'm still before chapter 4.
Wow. Impressive. You mainlined it huh?
Mechanical level 5 can be obtained via sidequest only. Level 4 is the peak upgrade with Eleanora.
Archeilogical was the one I upgraded next. Haven't seen biological that's above level 2 so far so archeilogical makes more sense to me.
